IPC: G08C23/04
Filed: 1980-10-17
Abstract: PURPOSE:To measure mechanically stably and precisely vibrations of large amplitude by constructing an inertial system with a weight and springs on its sides. CONSTITUTION:Light from a phot-transmitter 1 passes through an optical fiber 2a, a beam splitter 3 and an optical fiber 2b and reaches a sensor 13. The light is emitted with an angle determined by a constant N.A. from the end of a the optical fiber 2b. A part of the light is made incident on a lens of refractive index distribution type 4 which is installed at a weight 12, focused at a miller 17, reflected, passed through the optical fiber 2b, the beam splitter 3 and an optical fiber 2c, and lead to a light receiver 11. The weight 12 and springs 14a and 14b in the sensor constitute an inertial system. An object 10 to to be measured is attached directly to the sensor 13, and vibration starts. Then the distance X between the end of the optical fiber 2b and the lens of refraction index distribution type 4 changes corresponding to the vibration of the weight 12. The amount of light I incident to the lens 4 becomes I=AXl/(X<2>tan<2>thetamax), wherel is a radius of the lens 4 and thetamax is the maximum angle of emission of the optical fiber 2b.

Abstract: PURPOSE:To arrange liquid crystal molecules homogeneously and obtain a display element for color switching by sealing a liquid crystal in a cell then heating the cell up to the temp. at which the liquid crystal phase turns to a liquid phase, then allowing the same to cool and applying an electric field parallel with the substrates in the process that it returns to the liquid crystal phase. CONSTITUTION:Insulating films 2, 2 are formed of silica or the like on two sheets of glass substrates 1, 1, and further Al is vacuum-evaporated to form conductive thin films 3, 3. The substrates 1, 1 are joined by means of an adhesive agent 4, and a positive dielectric anisotropic nematic liquid crystal 6 is sealed. Next, while AC voltage is applied at 3kV effective voltage between the electrodes 3, 3 in parallel with the substrates 1, the cell is heated up to the temp. at which the liquid crystal phase turns to a liquid phase, after which the heating is ceased and the cell is allowed to cool. The applied voltage is switched off upon confirmation that the liquid phase has returned to the liquid crystal phase. In this way, the homogeneous arrangement is formed. If once formed, the orientation is stable. Polarizing plates are mounted to this cell and the cell is utilized as a photoswitching element by the rotation of the polarizing plates or the cell.

Title: Fluorescence-polarization measuring apparatus
Inventor: KOSHI HIROYUKI
IPC: G01N21/64
Filed: 1984-07-13
Abstract: PURPOSE:To shorten the measuring time, by sequentially inputting a polarization angle signal and a corresponding fluorescence intensity signal at a specified time interval, computing the parallel component and the orthogonal component of the fluorescence polarization degree based on two continuous signals, and obtaining the polarization degree. CONSTITUTION:A sample 4 is excited by light emitted from a light source 1 through a spectroscope 2 and a polarizer 3. The intensity of the fluorescence from the sample is measured by a detecting system 7 through an analyzer 5 and a spectroscope 6. The result is processed by an operator 9. The angles of the polarizer 3 and the analyzer 5 are controlled by a control system 8. At this time, the intensity of the fluorescence is measured at a polarization angle thetaEM=0 deg. by the polarizer 3 and a polarization angle thetaEM=01 deg.. Then the intensity of fluorescence is measured at an angle thetaEX=0 deg. and an angle thetaEM=theta2. Based on both intensities, the parallel component and the orthogonal component of the intensities of fluorescence are computed. The fluorescence polarization degree is obtained from both components. Thus the measuring interval of the fluorescence polarization degree can be set regardless of the rotary time of the analyzer 5.

Abstract: PURPOSE:To attain adjustment of a phase shift amount and a frequency characteristic by shifting phase difference between an input signal and an output signal by relatively shifting the positions of the electrode fingers of first and second surface acoustic wave resonators for a suitable amount. CONSTITUTION:Two surface acoustic wave resonators 103 and 104 are constituted while being adjacent to a piezoelectric plane 100 each other, and both the two surface acoustic wave resonators 103 and 104 form cross finger electrodes 109 and 110 to transmit/receive surface acoustic waves at the centers and a pair of reflectors 105-108 to reflect the surface acoustic waves on the both sides. Among the two surface acoustic wave resonators 103 and 104 at least, the relation positions between the cross finger electrode 109 provided in the first resonator 103 and the cross finger electrode 110 provided in the second resonator 104 are shifted for the prescribed amount. Thus, since the electrode finger position of the second surface acoustic resonator 104 is shifted against a displaced amplitude generated in the first surface acoustic wave resonator 103, the phase of a resonance current to be obtained in the second resonator 104 is shifted, and the function of a phase shifter can be added.

Abstract: PURPOSE:To recover the fault of a memory by providing a device to carry out a DMA bus cycle in preference to a retrial bus cycle if a DMA request is produced before the retrial bus cycle is carried out. CONSTITUTION:A DMA request is produced right before the retrial read cycle of a main processor 30 is carried out, and a DMA read cycle is carried out in preference to a retrial read cycle. In this case, a DMA bus occupation signal is outputted with a DMA request given from a DMA processor 40.
